VAPOR-STOVE.

SPECIFICATION forming pari: of Letters Patent No. 297,120, dated April 22, 1884.

Application filed August 15, 1893.

(No model.)

To ctZZ whom it may concern:

Be it known that I, FAY O. FARWELL, of Cresco, in the county of Howard and State of Iowa, have invented certain new and useful Improvements in Vapor-Burners and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in vapor-burners and means for attaching them to ordinary cook-stoves; and it consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a View in perspective of a stove embodying my invention. Fig. 2 is a view in section across the lines an x. Fig. 3 is a view of a skeleton plate. Fig. 4c is a sectional view ofa fluid-supply tank, and Fig. 5 is aview of the inductiontube.

A is a cook-stove of ordinary construction, and c is the ash-box thereof.

B is the supply-tank, made preferably of metal, and of sufficient size and shape to contain the pump @,which is located therein. The

tank B is provided with a recess, b, in the top thereof, the said recess being perforated to admit the entrance of the handle c, and of sufficient depth to permit the said handle c, when lowered,to be upon a level with the lid of the tank.

l) is a skeleton plate consisting of the rim d and the inwardly-bent arms d', the object of the bent arms being to support theburners F, which arelocated under the center of the plate.

The plates D are situated within the potholes of the stove and supported by the cover, and are provided with shields d2, which project beyond the rimcl to the edge of the stove, v

for the purpose of protecting the needle-valve E from damage from above.

H is the main supply-pipe in direct communication with the supplytank B and branch pipes G. The burners F communicate with the supply H by means of the branch pipes G.

The vapor-burner is so constructed that the vaporizing-tubes I rest in an inclined position, and is provided at one end withaneedle-valve coupling, .I by means of which the iiow of uid from the main supply-pipe H into the vaporiZing-tube I is regulated. The tube I is provided with a drip-opening, p, through which a small port-ion of the oil passes into the starting-cup M. At the end opposite the valvecoupling J is secured the needle-valve E, by means of which the ow of vapor into the induction-tube O. is regulated. This valve is placed upon suoli an angle as will serve to 6o bring the end c above the lid of the stove. This end of the burner is supported by the armsd, and is protected by the shield d2, as described.

L is the combustion-chamber, provided at the lower end with asocket or sleeve, Z,th1ough 65 which passes the vaporizing-tube I. This vaporizing-tube can be secured in position by a set-screw or other suitable device, and is situated directly above the starting-cup M, which latter is held in position by the screw Z.

N is a perforated cap, made in a single piece, and covering the combustion-chamber L, secured in position by the rim a, which latter is rigidly attached to the combustion-chamber L.

The induction-tube O is open at both ends, and is situated in a line with the screw-valve E. This tube is preferably constructed of brass, and the end thereof nearest the screwvalve is partly severed both longitudinally and transversely, for the purpose of forming 8o theflattened wings o,which latter form shields, as shown in Fig. 5. The object of these shields is to prevent the vapor, as it passes from the needle-valve E into the combustion-chamber L, from being ignited by the flame emitted from 8 5 the perforated cap N.

Having thus described the several parts of my invention, I will proceed to describe the operation of the same. After properly adjusting my attachment to astove, the tank B is sup- 9o plied with gasoline through the perforation da.

The oil is then forced to the burners by pneumatic pressure caused by operating the pump C. The screw-valve J is now opened, thus permitting asmall quantity of the fluid to pass into the starting-cup M, after which the valve J is closed and the fluid in the starting-cup ignited, thus producing a sufficient amount of heat to cause the fluid in the vaporizing-tube I to become vaporized. The valves E and J roo are again opened and a light applied to the burner, thus causing a flame to appear through the perforated cap N. vThe heat from this flame will vaporize the iiuid as fast as it enters the tube I. As the pressure inthe tankB becomes weaker than that generated in rthe tube I, the excess of pressure in the tube I escapes to the tank B, thus maintaining a constant pressure in the tank B without further assistance from the pump G.

The construction of my improved burner is such that it may be attached to an elevated tank by ruiming the main pipe up through the stove-pipe and out at a desired joint and connecting it with the supply-tank,which maybe located at the junction of thc joint or in any other desired place.

My device is simple in construction and durable and efficient in use, and can be made at.

a small initial cost.

It is evident that slight changes in the construction and relative arrangements of the scv eral parts of my improvement might be resorted to without departing from the spirit of my invention, and hence I would have it understood that I do not coniine myself to the exact construction shown and described, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

I am aware that it is not new to provide'an oil-stoVe stand with skeleton plates, burners, main and branch pipes, and a reservoir, also, that itis not new to provide the reservoir with a pump for forcing the oil up to the burners, and hence I make no claim thereto. In my device I. employ skeleton plates adapted particularly for ordinary cooking-stoves, and conneet the burners which are seated on the skeleton plates to the reservoir by a main and branch pipes. This enables an ordinary cooking-stove to be easily and cheaply con- Verted into an oil-stove without changing the structure of the stove or damaging it in the least.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In combination with an ordinary cooking stove, a supply-tank placed in the ash-box of the same, a pump situatedin the supply-tank and forming a part thereof, burners situated in or under the pot-holes of the stove-top, a single supply-pipe attached to the tank, and intermediate connecting -pipes between the burners and the mainl supply-pipe, substantially as set forth.

2. In combination with an ordinary cook ing-stove, an oil-supply tank situated in the ash-box thereof, and provided with a pump for forcing the oil up to the burner, skeleton plates situated within the pot-holes and supported by the stove-cover, vapor-burners supported on the skeleton plates, a main supply-pipe7 and intermediate connecting-pipes connecting the burners with the main supply-pipe, substan tially as set forth.

'Ihe combination7 with skeleton plates situated within the pot-holes of an ordinary cook-stove, and supported by the cover thereof, said plates being provided with lateral shields (Il, of vapor-burners supported on said skeleton plates and provided with screwvalves, which latter rest under the shields7 a supply-tank, a main supply-pipe, and branch pipes connecting the burners and main pipe, substantially as set forth. v l

4. The combinatiomwith the tube I, screwvalve coupling J, screw-valve, and dripcup, of the screw-Valve E, the split tube O, constructed as described, and the cap N, all of the above parts combined and adapted to operate as described.

In testimony whereof I have signed this specification in the presence of two subscribing
